Answer:

x=0 and y=−8

Step-by-step explanation:

4x+4y=−32

4x−4y=32

Add these equations to eliminate y:

8x=0

Then solve 8x=0 for x:

8x=0

(Divide both sides by 8 to get x by itself)

x=0

Now we plug x back in to solve for y.  

4x+4y=−32

Substitute 0 for x

(4)(0)+4y=−32

4y=−32 (Simplify both sides of the equation)

(Divide both sides by 4 to get y by itself)

y=−8
